3DMark11 wont see my pair of MSI GeForce GTX550ti Video Cards

I am having trouble getting 3dMark11 Advanced Edition detecting both of my video cards to run with multi-gpu. The GeForce Control Panel, and OpenGL benchmarks detects the multiple GPUs.

I have also tried editing the profile by hand using a import/export tool, and by editing the profile in the GeForce Control Panel and telling 3dMark11 specifically that that are 2 video cards in crossfire.

I am running the latest GeForce 270.61 drivers, and the latest patch to 3DMark Version 1.01, and SystemInfo 4.0.

You are getting zero score because the benchmark run was not done with default settings, that's not related.

CPU detection issue is our bad, will get it fixed.

As to the SLI detection, everything in this data points to a single GPU only but we'll investigate further (obviously I believe if you say you have two cards - it is just that our SLI detection routines seem to disagree with the reality)

Thanks for the update. I only had time this morning before work to run those 2 quick tests.

Is there anything specific you need to me get (as far as system info) goes to help your figure out why the SLI detection routines are not detecting my pair of video cards.

I just tested with Portal 2, and set everything to the highest settings and pretty sure its finding both cards... as performance in the game is great. Though its my first game (I am not a "normal" gamer - I built the system to do 3D Animation, and Video Production), but bought a couple of games as a diversion.

FMSIDiag.exe can also be used to switch between two different SLI detection routines. By default the legacy routine is enabled but if you disable it and enable the other routine, this could, in theory, change things.

The reason we still use the legacy routine by default is that otherwise SLI detection breaks for a large number of configurations (for reasons we honestly haven't figured out yet)
